Application tiled August 1916. Serial No. 116,914."

To all whom t may concern Be it known that l, PHILIP DHUC Danss- Lnn, a subject of the King of Great Britain and Ireland, residing at London, England, have invented Methods of and Means tor Supporting Tiles, More Especially lFJhile Subject to Heat Treatment, of which the Yfollowing is a specification.

This invention relates to the supporting of tiles, more especially lwhile subject to heat treatment, as 'for example when being gloss fired.l For the latter' and like purposes the method or" supporting tiles in the vertical plane balanced upon two points of contact in saggars, as nearly upright as is consistent with the stability ot the tile, in contradistinction to other methods where theplane el each tile is horizontal, is recognized to be advantageous from the point of view of reducing the proportion of the mass of thesupporting material to that of the tiles supported. But even so, this method oll supporting tiles, as aforesaid, in saggars, wastes much space, involves the heating uselessly of a ot material which is still large in proportion to the mass ot the tiles supported, and necessitates considerable ein,

pense in replacing broken saggars New the object of the present invention is to enable'the space in ovens and mailles to be employed to greater advantage than has solar been possible and it is achieved by providing for the support vot the tiles in the vertical plane in rows which can be added to vertically without the necessity oi using supplemental horizontal carrying bases, the whole forming a symmetrical and compact nest or stack in which the mass ot supporting material in relation to the tile mass is considerably reduced and space economized.

According to the invention the tiles are arranged to be stacked in pairs in the usual way, that is to say, back to back touching, and tace to tace but slightly apart, in hori zontal rows with their edges resting upon the keen arrises ot rods or saddle backs of refractory materials, carried inV horizontal rows limited only in number by considerations ot the cross sectional area ot the oven or mullle to be used.

These rods may becarried by walls each made in one slab or of a number of slabs ot material appropriately united together7 although in many cases it isthought that it may.` be more convenient to constitute the walls of bricks' which can be built up tier by tier as the work ol" supporting the tildes 1n rows proceeds. The rods or saddlebacks may be passed through holes in the walls, be adapted to rest on brackets carried by the walls, or be supported in both ofthese ways.

In the accompanying drawings, Figures yl and 2 are elevations at right angles to each other illustrating one way of carrying the invention into effect.

F ig. 3 is a detail view showing in side ele vation a modification. A

Fig.V 4 is a part plan showing a further modification.

According to the example shown in Figs'. l and 2, a series of rods or saddle backs a of a double channel shapein cross section and made of refractory material are em ployed ofa length necessitatinga pair oit end walls Z2 and two intermediate Ywalls c for their support, assuming that the plat form A of a truck tor use in a tunnel oven is to be loaded. Each wall Z) or c may be built up of bricks al, c the majority (Z of which are of a length equal say to twice the height, although the length ofeach ofthe others c is say three times that of the height, rendered necessary for purposes of bonding. Recesses 7 in the upper or under horizontal faces of these bricks, or in both of such faces, as in the example shown, serve to accommodate the rods or saddle backs a the majority of which latter support tiles giarranged at opposite sides thereof. In the longer bricks e any tendency ol the rods a. to spread, owing to the lateral thrust of the tiles g thereon, is resisted by the Vtact that recesses y for a pair of rods a are 'formed therein, and the same tendency to spread which exists between the shorter bricks cl, where each supports a single rod t isor may be resisted by interlocking means such as a key h, adapted to enter recesses k1 in the companion faces of adjacent superposed bricks. Or as shownl in Fig. 3, a lug z' on one face of such a brick may be adapted to enter a recess y' in the companion face ot' a brick in the next adjacent row.y

As will be-seenthe tilesg are arranged vertically in longitudinal rows, each row" being supported by and between the keen arrises a1 on two laterally adjacent rods ct there being a number of such longitudinal rows arranged to form a vertical series of superposed horizontal sets of such rows.

yln this eXample it has been assumed that only one size of square tile g is to be accommodated but it will be understood that by appropriate choice in the number of rod or saddle back supporting regions in the various bricks composing the walls b, c and by suitably proportioning the height of the bricks and varying the number employed between rows of rods or saddle backs a, a wide range of sizes and shapes of tiles y,can be economically dealt with.

lnstead of using a number of long rods or saddle backs extending the width of the set of walls as in Figs. 1 and 2, a number of shorter ones each extending between adjacent pairs of walls may of course be used, if desired, as shown in Fig. a. 1n this case the shorter rods or saddle backs a are supported on brackets la on the walls b c.

The bricks of which the walls are built up may be dust pressed in steel dies, thus giving very regular and true shapes, facilitatn ing assembly, and they may be more or less hollowed or recessed as shown at m in Fig. 2, or perforated as shown at n in Fig. 1, to reduce their weight, while enabling a broad and stable base to be maintained.

Vhat 1 claim is z- 1. The method of treating tiles, said method consisting in arranging the tiles with their surfaces vertical to form a plurality of horizontal rows of tiles and supporting the rows of tiles in superposed parallel sets, the edges of the tiles being inclined to the horizontal and the horizontal rows of tiles in one set being arranged in staggered relationship and parallel to those in an ad jacent set.

2. The method of treating tiles, said method consisting in arranging the tiles, withtheir surfaces vertical, in horizontal rows, supporting the rows of tiles in superposed parallel sets and in staggered relationship, the rows of tiles inone set extending into the angular spaces between the sides of the rows of tiles in an adjacent set or sets and firing the tiles while supported in this position.

3. For supporting tiles in a vertical position, a plurality of rods spaced apart horizontally and vertically to form horizontal rows with the rods in one horizontal row out of vertical alinement with those in adjacent horizontal rows and means for supporting said rods in position.

4. For supporting tiles in a vertical posi tion, a base piece, transverse walls disconnected from each other and spaced apart upon said base piece, each wall being built up of separate bricks or blocks placed freely one upon the other and a plurality of hori zontal rods carried by and extending through said walls, said rods being spaced apart and arranged to form superposed horizontal sets of rods.

5. For supporting tiles in a vertical position, a plurality of rods spaced apart in horizontal rows and transverse walls adapted at a number of successive levels to support Said rows of rods one above the other to any desired extent, the rods in one horizontal row being out of vertical alinement with those in adjacent horizontal rows.

t. For supporting tiles in a vertical position, a plurality of rods spaced apart in horizontal rows and transverse walls adapted at a number of successive levels to support said rows of rods one above the other, the rods in one row being out of vertical alinement with those in adjacent rows and the walls being constituted of loose bricks that can be builtup tier by tier as the work of supporting the tiles on the rods proceeds.

7. F or supporting tiles in a vertical position, a plurality of rods, transverse walls built up of bricks resting freely one on the other and adapted to support said rods to form a vertical series of superposed horizontal rows and means for lockin said bricks together sidewise to resist lateral thrust on the rods due to the tiles supported thereby.

8. F or supporting tiles in a vertical position, an openwork structure comprising a base piece, transverse walls spaced apart and carried by said base piece and disconnected from each other and a plurality or rods or saddle backs of refractory material carried by said walls and arranged in super posed horizontal rows, each rod being formed with keen arrises adapted to engage and support the edges of tiles arranged with their surfaces vertically, and said walls being constituted by loose bricks which can be built up tier by tier as the workof placing the rods or saddle backs in position and the tiles thereon, proceeds. f

9. F or supporting tiles in a vertical position an openwork structure comprising a base piece, disconnected parallel walls carried by said base piece and formed with horizontal rows of apertures at different levels the apertures in one horizontal row being out of vertical alinement with those in adjacent rows, and a plurality of rods of refractory material extending through the apertures in said walls and formed at their sides with keen arrises adapted to engage and support the edges of tiles placed vertically between laterally adjacent rods.

10. For supporting tiles in a vertical position, an openwork structurecomprising a platform, separate walls carried by said platform and composed of bricks resting freely one on the other and arranged in tiers, adjacent superposed bricks in each wall being shaped to form apertures between them, and a plurality of rods extending through the apertures in the walls and forming horizontal rows of rods, the rods in one horizontal row being out of vertical alinement with rods in adjacent horizontal rows.
